Mawu Oyamba
Sodium borohydride ndi mankhwala osakhazikika. Ndi ufa wolimba womwe umasungunuka mosavuta m'madzi ndipo umapanga njira ya alkaline.
Sodium borohydride ili ndi mphamvu zochepetsera ndipo imatha kuchitapo kanthu ndi zinthu zambiri zakuthupi. Amagwiritsidwa ntchito kwambiri popanga organic synthesis ndipo nthawi zambiri amagwiritsidwa ntchito ngati hydrogenating agent. Sodium borohydride imatha kuchepetsa ma aldehydes, ma ketoni, esters, ndi zina zambiri ku ma alcohols ofanana, komanso imachepetsa ma acid kukhala mowa. Sodium borohydride itha kugwiritsidwanso ntchito mu decarboxylation, dehalogenation, denitrification ndi zina.
Kukonzekera kwa sodium borohydride nthawi zambiri kumapezeka ndi zomwe borane ndi zitsulo za sodium. Choyamba, zitsulo za sodium zimakhudzidwa ndi hydrogen kuti zikonzekere sodium hydride, kenako zimachita ndi trimethylamine borane (kapena triethylaminoborane) mu zosungunulira za ether kuti zipeze sodium borohydride.
Sodium borohydride ndi mphamvu yochepetsera yomwe imagwira mwachangu ndi chinyezi ndi mpweya mumlengalenga kutulutsa haidrojeni. Chidebecho chiyenera kutsekedwa mofulumira ndikusungidwa mouma panthawi yogwira ntchito. Sodium borohydride imagwiranso ntchito mosavuta ndi zidulo kutulutsa mpweya wa haidrojeni, ndipo kukhudzana ndi zidulo kuyenera kupewedwa. Sodium borohydride nayonso ndi poizoni, ndipo chisamaliro chiyenera kutengedwa kuti tipewe kupuma kapena kukhudzana ndi khungu. Mukamagwiritsa ntchito sodium borohydride, valani magolovesi oteteza ndi magalasi, ndikuwonetsetsa kuti ntchitoyi ikuchitika pamalo abwino mpweya wabwino.
